Abstract: A resin-made pipe is provided, the resin-made pipe containing: a liquid crystal polyester resin composition as a formation material, in which the pipe has a bending part, a melt viscosity of the liquid crystal polyester resin composition satisfies Formula (A), and an arithmetic mean roughness (Ra) of an inner surface of the pipe in an extension direction is 0.2 µm or more and 5 µm or less. B / A ≤ 10 (A is a melt viscosity of the liquid crystal polyester resin composition at a temperature being a flow starting temperature + 20°C, and B is a melt viscosity of the liquid crystal polyester resin composition at the flow starting temperature.)

Abstract: The present disclosure relates to a polyester resin blend, a polyester film and a preparation method of the same. The polyester resin blend is capable of providing a heat shrinkable label that is transparent and has excellent shrinkage even if it contains recycled polyethylene terephthalate as well as virgin polyethylene terephthalate. In addition, the heat shrinkable label can be reused while attached to a PET container, etc., and is expected to be useful for providing continuously usable plastics that have been recently attracting attention.
